ROAD MARKER Filed y 1951 Patented July 11, 1933 UNITED STATES 1,918,099 PATENT OFFICE GEORGE E. HANKS, OF CLINTON, NEW JERSEY, ASSIGNOR TO TAYLOR-WHARTON IRON AND STEEL COMPANY, OF HIGH BRIDGE, NEW JERSEY, A CORPORATION OF NEW JERSEY ROAD MARKER Application. filed July 22, 1931.. Serial No. 552,517.

The invention relates to indicators of the mute or marking type for delineating lanes of trafIic or zones of safety on public high ways and the like, and provides a road marker possessed of decided advantages over the known art.

The principal object of the invention is to provide a road marker of exceedingly simply construction so that it readily lends itself to casting or other modes of manufacture and can be applied with facility and dispatch and replaced when necessary without marring or damaging the pavement, and which withal is not susceptible to casual displacement.

The nature of the invention consists in the provision of a road marker, which in one aspect has openings inclined from the perpendicular and towards each other for directing driven fastenings, such as spikes and the like, so that their points tend to cross or to converge in the region of the vertical axis of the marker, the effect of which is firmly to resist lifting effort tending to loosen or dislodge the marker; and said road marker, in another aspect, having angularly directed driving openings, as stated, and having a driving shank or stud formed to engage or interlock with the converging ends of the spikes or other driven fastenings.

The invention is illustrated in the accompanying drawing wherein Figure 1 is a top view of a marker constructed in accordance with my invention.

Fig. 2 is a sectional View of the same applied.

Fig. 3 is a sectional view of a modification in which the mark is formed with a driving shank or stud having a slot whereby interlocking relation is established between the stud and the spikes or other driven fastenings.

Fig. 4 is an elevational View taken angles to Fig. 3.

Fig. 5 is a sectional elevation showing the application of the slotted stud construction.

Fig. 6 is an end view and,

Fig. 7 is a sectional View showing the invention applied to a marker having end calks or pilot lugs.

In its simplest embodiment the invention partakes of a head or main body having a crowned surface 5 and a substantially flat bottom 6 adapted to take a flush bearing when at right emplaced on apavement or roadway. The

head or marker may be formed of bright altical axis of the marker, the effect of which is adequately to resist lifting effort imposed upon the marker. The application of this embodiment is shown in Fig. 2 which shows the marker emplaced upon a pavement and secured to place by angularly or crosswise ranging spikes 8 or other driven fastenings.

Referring to Figs. 3, 4 and 5, and according to another form of my invention, the marker in addition to the openings 7, is formed or provided with a driving shank or stud 9 which may be formed or adapted so that it will cooperate with the crosswise ranging, driven elements positively to resist casual displacement of the marker. One way of accomplishing such cooperation is to provide the stud with a transversely ranging slot 10 in line with the angularly directed openings of the head so that the spikes or other driven fastenings will penetrate said slot in a crosswise direction as shown in Fig. 5.

According to the embodiment shown in Figs. 6 and 7 end calks or pilot lugs 11 may be employed in association with thenovel guide openings 12.

Having described the invention, I claim A road marker comprising a unit cast head and shank having cooperative openings, the

structure having the characteristic that portions of the head are angularly disposed with relation to its flush bearing surface and that the openings of the head are radially inclined in coincidence with the angle so that spikes or the like driven fastenings will be guided in positive fashion by said openings so as to intersect in the opening of the shank.

In testimony whereof, I aflix my signature.

GEORGE R. I-IANKS.
